SPEGIFIGATION forming part of Letters Patent No. 514,629, dated February 13, 1894.

Application filed February 27, 1893. Serial No. 463,861. (No model.)

.To all whom it may concern:

Be it known that we, JAMES STAPLETON and ROBERT I RAY, citizens of the United States, residing at Rays Mills, in the county of Berrien and State of Georgia, have invented a new and useful Roller Cotton-Gin, ot which the following is a specitication.

This invention relates to cotton gins; and it has for its object to provide an improve- 1o ment in machines of this character whereby the operatic g devices therefor will be greatly simplified, rendered more efficient in operation and protected from dust, grit, dac.

To this end the main and primary object of the present invention is to provide a simi ple and ecient cotton gin.

With these and many other objects in view which will readily appear as the nature of the invention is better understood, the same zo consists in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustrated and claimed.

Referring to the accompanying drawings:- Figure l is a perspective viewot a cotton gin 2 5 constructed in accordance with this invention. Fig. 2 is a side elevation thereof, the inclosing face plate and one of the stripper bar adjusting plates being removed. Fig. 3 is a central vertical sectional view thereof.

3o Figxe is acentral longitudinal sectional View. Fig. 5 is an enlarged vertical sectional view showingthe eccentric connections with the stripper bar ends; Fig. 6 is a detail in perspective of the feed board. Fig. 7 is a similar view of the stripper bar and blade. Fig. 8 is a detail sectional view of the eccentric arm connection to the connecting links.

Referring to the accompanying drawings, A A represent opposite triangularly shaped framesides between vwhich are arranged the ginning devices to be described. The said frame sides AA are provided at one side near their upper ends with the bearing boxes B, which receive the journal ends of the ginning roller O, to one end of which is connected the band wheel or pulley c, from which motion is communicated to the roller in the direction indicated by the arrow. Directly under the gin roller C, and connecting the opposite rear edges of the frame sides A, is the inclined back board D, in which are arranged the doors t), by means of which access may be gained into the space between the frame sides for the purpose of oiling, fisc.

Directly above the bearings B, the opposite frame sides A, are provided at their upper rear edges with the slot-s or pocket-s E, which adj ustably receive the opposite ends of the stationary blade head or bar F. The stationary blade head or bar F, is arranged transversely between the frame sides A, and carries a stationary retaining blade G, which is disposed in close proximity to and at one side of the roller C, so that the cotton being ginned is drawn through the space between the blade and the roller, and discharged at the back end of the gin, in the ordinary manner. The ends of the head or bar F are free to move laterally and vertically in the slots E, of the frame sides, and maybe adjusted either vertically or laterally in such sides by means of either the screws H, passing into the top of the slots or recesses E, or the screws I, passing through the slots fi, at one side of the slot E, in order to provide means whereby the retaining blade G, can be adjusted toits proper height, as well as to and from the gin roller in order to regulate the width of the space through which the cotton is drawn.

Arranged to reciprocate vertically below and at one side of the retaining blade G, is the vertically reciprocating stripper blade J. The vertically reciprocating stripper blade J, extends transversely and entirely across the space between the frame sides A, and is secured fast at one end to the vertically movable and laterally adjustable stripper bar K. The opposite ends of the stripper bar K, work vertically in the slots 7o, in the opposite sides A, and loosely engage the upper slotted ends of the vertically reciprocating guide blocks L, sliding in the guide grooves Z, formed in the outer sides of the frame sides A. The ends of the bar K, are free to move laterally in the upper slotted ends of the blocks L, and,

projecting beyond the same, tit in the notches M, formed in the inner faces of the opposite bar adjusting plates m., laterally adjusted on the outer faces of the sides A, on the screws m', as will be apparent. By adjusting the bar adjusting plates m, on the sides A, the stripper blade can be moved to and from the retaining blade, so that the stripper can be adjusted to be adapted to the particular cotton being ginned.

Below the vertical guide grooves l, in .the Opposite frame sides A, are formed the enlarged pockets or recesses N, in which work the operating eccentric disks N', keyed on the shaft n, journaled in siiitablebearings on the sides A, and extending beyond the same, said shaft carrying upon` opposite ends the pulleys O, one of which receives motion from suitable driving machinery, while the other by means of the belt o, transmits motion to the band wheel or pulley c, as clearly shown in the drawings. The eccentrics N', working inside of the pockets in each of the frame'sides A, work inside of the eccentric straps P, from which extend the threaded eccentric arms Q, passing through perforations in the lower `end of the connecting links R, and carrying the adjusting nuts r, working inside of and out of the links R, so as to adjustably connect the eccentric arms thereto. The upper ends of the connecting links R, are pivotally connected to the lower ends of the sliding blocks L, so that as the shaft fn, rotates, through the medium of the eccentric connectionswith the sliding blocks L, the stripper blade is given a reciprocating motion in front of the retaining blade, so that as the latter blade holds the cotton in position to be drawn therefrom by the gin roller, the stripping blade strips out the seeds as will be readily understood, the falling seeds passing onto the inclined breastboard S.

The inclined breast-board S, is arranged between the opposite frame sides A, so as to have the upper end extend under the reciprocating stripper, in order to catch the seed and carry the same away from the gin, while the cotton is fed to the roller and the stripping devices by the inclined feed board T.

The inclined feed board T, is adapted to have the opposite edges thereof loosely engage the inclined grooves t, formed in opposite inner sides of the sides A, in front of the stripping devices, so that the said feed board can be readily moved in and out of position. The said feed board T, carries at its lower inner edge, the comb or series of fingers U, which serve to hold the cotton being ginned, While at the same time allowing the seeds to pass therethrough and onto the breast board or seed apron S.

Now it is thought that the construction and operation of the herein described gin will be readily apparent. The cotton to be ginned is fed onto the board T, and of its own weight falls to the stripping devices. When the stripper blade is in its lowest position, the

roller C, will take hold of the cotton and draw it through the space there-between and the stationary retaining blade which retains the cotton in such a position so that the ascending stripping blade will strip out the seed and allor7 the same to drop onto the breast board or seed apron, while the roller continues to draw the cotton through. It may be observed at this point that face or cap plates U', are removably secured to opposite sides of the frame sides A, to inclose the pockets thereof and the devices in such pockets, so as to keep the same freefrom dust, grit, dac.

Changes in the form, proportion and the minor details of construction as embraced within the scope of the appended claims may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is U I. In a cotton gin, the combination of agin roller, a stationary retaining blade disposed at one side of and in close proximity to the roller, vertically reciprocating guide blocks, and a bar carrying a stripper blade moving below and at one side of the retaining blade, said bar having its ends adj ustably connected to said guide blocks, substantially as set forth.
